SPECIFICATION forming part of Letters Patent Na/18,987, dated May 8, 1900.

Application filed February 15, 1899. Serial No. 705,528. (No model Z'o all whom t may concern.:

Be it known that I, SYDNEY CHARLES Norr, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Double Acting Compressing Devices; andIdo hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of ro reference marked thereon, which form a part of this specification.

This invention relates to an improved compressing device adapted to be used for the purposes usual for devices of the kind, and esr 5 pecially for the purpose of a temporary binder for loose sheets of paper-such as bills, invoices, and the like-or for account-books, wherein it is desired that the account may be removed from the book when completed and zo other new leaves substituted. v

The invention embraces a device whereby the action of a right and left threaded shaft, to which are secured fiexible connecting parts, also connected with the opposite ends of a 2 5 movable binding-plate, is utilized to dra-w the said plate into binding contact with a base ,or any body placed between the said plate and the base.

The invention consists in the matters more 3o fully set forth and defined in the appended claims.

In the drawings, Figure l is a View illustrating `a device embodying my invention. Fig. 2 is a section taken on line 2 2 of Fig. l.

Fig. 10 illustrates marginal notches. in a sheet of paper adapted to be used in the modified form of my device. Fig. 1l is a detail shown in section, partly broken, of a modification of=my invention, by means of which the capacity of the same may be 5o greatly increased. Fig. l2 is asection taken on line 12 12 of Fig. 1l. Fig. 13 is a perspective rear elevation of a binder embodying my invention, illustrating a modification thereof. Fig. let is a perspective view of one of the details of my invention.

As shown in the drawings, A indicates a tube having end bearings a a' and a central bearing a2. A right and left threaded screwshaft B is journaled in the said bearings and is provided with an angular end, which projects through t-he bearing a and is adapted to be engaged by a key G. C C are carriages movably mounted on opposite ends of the said screw-shaft and provided with internal screw-threads complementary thereto, whereby the said carriages may be oppositely driven by the rotation of the shaft. The said carriages preferably fit closely within the said tube A and slide between the Walls thereof, whereby all lateral movement of the said car- 7o riages is prevented, while a free longitudinal movement is permitted.` A is a movable binding-plate, and D D' are flexible bands or other suitable connections, preferably of metal, secured at one end to said carriages and at their other end to the extremities of l the said binding-plate. Convex bearing-snrfaces d3 a4, located at the ends of the said tube and over which the flexible bands D D pass, are adapted to cause the strain of the 8o carriages upon the said bands to be converted into a direct downward pull upon the said movable binding-plate.

The tube A of my improved binding device may be of any desired construction or form. As herein shown, the cross-section thereof is rectangular and the length thereof is approximately equal to the width of the book or material to be compressed. As herein shown, it is constructed of separate side, top, and bot- 9o tom plates d5 a6 al as, respectively, joined by rivets or other suitable means. Obviously, however, the said parts may be integral, and I do not wish to be restricted t0 a construction wherein the parts of the tube are separate plates. If constructed of separate plates, the bottom plate as is provided at its ends with integral upwardly projecting parts adapted to form the lower half of thebearings in which the ends of the said shaft B are j ournaled. Rigidly secured to the side plates are end pieces a9 am, the under sides of which IOO ' form the top portion or upper half ofthe bearing for the said shaft. The said end pieces have inwardly and downwardly inclined concave inner surfaces. The top plate is provided at its extremities with integral downwardly and inwardly inclined cylindrical convex ends a3 a4, complemental to the concave surfaces of the parts a9 am, heretofore described, fitting into the same and providing transverse passages in the ends of the tube, through which pass the iiexible bands heretofore mentioned. The central bearing-block ci? is situated transversely in thev said tube and is provided with a cylindrical aperture longitudinal of the tube and is adapted thereby to form a bearing for the said screwthreaded shaft B, which is provided with a central journal for that purpose. The said shaft is preferably located near the bottom of the tube and is provided with a right-hand thread on one side of the central bearing and with a left-hand thread on the other side of said bearing, and at one end is provided with an` angular part, which extends outwardly through an end bearing and is adapted to be engaged by a key G, as shown in Fig. 2. The carriages C C are internally screw-threaded complementary to the screw-threads upon the said shaft and are adapted to be moved by the rotation of the said shaft oppositely to each other. -They are also provided at the sides adjacent to the sides of the tube with upwardly-projecting integral arms c' c2,whieh extend to the top plate, and cylindrical pins c c in each carriage pass through the said arms, and to each of said pins is secured the looped end of one of the iiexible bands D or D. The said bands D D' extend outwardly through the passage in the end of the said tube A and upwardly therefrom into engagement with the movable binding-plate A. 'The manner of attaching the said bands to the said bindingplate may be any convenient method. As shown in Figs. 1, 2, and G, the extremities of the said binding-plate are rounded off and the ends of the said bands D D' are turned over from the opposite extremities of the said movable binding-plate and secured thereto by screws or rivets. Obviously, however, other means of attaching the same to the plate may be used without departing from the principle of my invention, and I do not desire to be restricted to the specific means described. The manner herein shown of attaching the said iiexible band to the said carriages is as follows: A pertures d2, corresponding with the apertures in the carriages in which the pins c are held, are formed in the side plates of the said tube, the screw-shaft is rotated until the apertures in the said carriages come in alinernent with the apertures in the said tube, the end of the flexible band is then placed in position between the arms of the carriage, and the pin c is pushed into position in the carriage through the loop in the end of the band. The rotation of the shaft will then carry the carriages to any desired point, and it is obvious that when the carriages are moved from their position the said pins will be held in place by the side. walls of the said tube. As a modification of my device flexible cables D2 D2 D3 D3 may be employed instead of the said iiexible bands, in which case the said convex segments a3 a4 may be used, as heretofore described, or preferably rollers or grooved pulleys E E E E' may be pivoted in the ends of the said tube in such manner as to receive the said cables and change the direction thereof from parallel to the said screw-shaft to a direction perpendicular thereto, as shown in Fig. 7. In the use of the said cables a cable will preferably be attached on each side of each of the said carriages C2 C3 at points in line with the central axis of the said shaft and on each side thereof, and the said pulleysE E E E are of such diameter that the said cables draw on each side of the shaft parallel to the central axis, so that the said carriage draws true with the thread upon the shaft. The shaft B2 is provided with end and central bearings simi'- lar to those heretofore described and has also an angular end extending through one of the end bearings into position to be engaged by a key G or other suitable rotating device. Inasm uch as the use of the said cables will preferably cause the ends of the saidtube to project somewhat beyond the point where the said cables emerge from the said tube, it is preferable that the paper F to be bound therein vshould be provided upon its rear margin with notches ff, as shown in Fig. l0. This provides a means whereby the paper may be evenly adjusted within the said binder by releasing the paper from the binding act-ion of the movable binding-plate and' by pushing the paper rearwardly against the said cables. After the paper is in position the said binding-plate may be drawn downwardly upon the same to any required degree of tension by means of a key, (herein indicated by Gr.)

As a modification of my invention I provide means for increasing the capacity of my binder, as illustrated in Figs. 1l and 12, as follows: The binding plate A2 is provided with integral downward ly extending side walls, and at each end is provided with a convex upwardly and inwardly inclined transverse tension-bar am, integral with the side walls and designed to furnish a bearing-surface for the iiexible bands D and D', respectively. On each side of the center of the said binding-plate are transverse apertures,which extend through the integral side walls thereof and are adapted to receive cylindrical pins c3 c4, upon each of which one end of one of the said flexible bands is secured in a manner similar to that by which the other end is secured to the carriage C or C', as heretofore described. At each end of the binding-plate, equidistant from the center and closely adjacent to the said transverse tension-bars, but between the same and the center, is an aperture similar to those heretofore described as located near the center of the plate and adapted to receive therein the pins c3 c4, upon IIO , than the flexible bands D or DC O vestaca? e which are secured the looped ends of the bands D and D', respectively. The said pins may be secured in the said apertures in any convenient manner; but preferably the said pins are bolts screw-threaded at one end, adapted to engage a complemental screwthread in the side wall of the binding-plate and with a slotted head adapted to fit into the aperture of the other side, which is countersunk for that purpose, as shown in Fig. 12. The advantages of this construction are obvious, inasmuch as it provides a means for nearly doubling the capacity of my binder. It is believed that with the ends of the bands D D secured upon the pins c3 c4 when near the center of the binding-plate the device will be of sufficient capacity for all ordinary purposes; but should greater space be required it is only necessary to remove the pins to their positions near the ends of the bindingplate and secure the bands thereon, when it is found that the binder will hold nearly double the amount previously contained. v

As a further improvement I provide a thin plate I-I, of metal or other suitable material, having a length approximately equal to that of the binding-plate A and slightly wider The said plate is provided at each of its ends with a transverse notch or slot 7L, whereby the said plate is adapted to engage the said bands D and D', respectively, and prevent the same from bowing outwardly when the strain is rcmoved therefrom.

In devices of this description it may be preferable to provide a base hinged tothe said tube, or one may be constructed integralA therewith, as shown in Fig.. l, which illustrates a binding-clip such as will be used for invoice-sheets, bills, or other sheets which it is desirable to temporarily retain upon the desk-board. I do not, however, desire to be restricted to any specic form of cover to be used in connection with this binding device, but desire to claim, broadly, as a compression device, and have herein illustrated but one of the many uses to which my invention can be applied.
